I've just had my waterpump and cambelt changed also my alternator belt, I now have a whining noise when driving and it was not present before the belts were changed. Has anyone had a similar issue or any idea what it could be? I was thinking it could be too tight but the car runs fine, the mechanic I have used for years with no issues before. Any help will be greatly appreciated thanks.

It does sound like the belt is to tight which should not happen normally happen, sometimes the drive belt can also  be to tight you need to check tension on drive belt first should be able to turn belt half a turn sideways  on the longest part  of the belt with a bit of  resistance,  if at all possible you could remove this belt and see if noise goes away, if still there you need to get cam belt checked out  as  some garages don't change the tension pully and bearing when changing the cam belt and just  cut half the old belt off then push the new belt on the pullies and finally cut the old one right off and then push new one in place, which would then make the new belt to tight as the tensioner takes up the slack on the old belt as it stretches,  you really need to check if these parts have been fitted as if not the belt could snap leaving you with a very big bill

Thanks I know the old belt wasnt cut off as I've seen it, and best get it checked ASAP, I was wondering if it could be just with it being new the reason for it making noise. Thanks for your reply 👍
